Producer: Thomas/Rosenthal, Germany
Materials: stainless steel + toughened glass

A large tray with a metal ring and a clear glass base.

The curved profile supports the base which sits half-way giving the effect of suspension to its contents.
Visually made out of two components (spun stainless steel and toughened glass), it actually contains a 3rd metal part that holds the parts together.

The name Colla means glue in Italian and it was chosen for the absence of this material.
